Having moved away from old fashioned linear power supplies and Class AB output stages, NAD has developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has resulted in some of the best performing amplifiers regardless of basic design principle. The overall design of the C 268 is very linear over a wide bandwidth, providing dramatic advances over previous models with consistent performance into all speaker loads.
The power supply of the C 268 is capable of nearly 200 watts continuously and over 500 watts instantaneously, allowing for short term musical transients. NAD’s innovative asymmetrical PowerDrive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce the most demanding music without distortion or compression. It can also operate with any AC mains voltage from 100V to 240V, and provides pure DC power to all the various stages of the C 268. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.
The C 268 uses a customised version of the proven Hypex UcD output stage. This allows for massive power with nearly immeasurable distortion and noise in the audible range. Every detail of this design has been carefully crafted and perfectly executed to wring out ever last drop of performance.
